BUNDLE-CARRIER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 361,977, dated April 26, 1887.

Application filed March 12,1855. Serial No. 158,622.

To aZZ whom it may concern: 1

Be it known that 1, WILLIAM R. BAKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have 5 invented certain new and useful Improvements in Bundle-Carriers for Grain-Binders, of which the following is a specification.

In that type of bundle-carriers which swing or tilt transversely to the line of advance of the machine, so as to open a gap between themselves and the binder-decking or dischargechute, through which gap the load is deposited on the ground, difficulty has been experienced in making a clean and compact dump, owing I to the fact that the floor of the carrier remains parallel with the advance, and being, as a rule, composed of slats, these catch the sheaves and twist them around and leave them lying awry and scattered as the machine passes on. This I propose to remedy by supporting and tilting the carrier on different axes at front and rear, which is most effectively done by suspending it on pivoted arms or bails, the rear aim being the longer, so that when swung out to dischage a load the rear of the carrier will be taken farther from the binder than the front, leaving a wider gap at the rear, whereby the onward movement of the machine will tend to take the flooring away from the sheaves discharged, in- 0 stead of scraping it past them. With such carriers, also, it requires an expenditure of considerable force to open them for the discharge of the accumulated load, and if this is thrown upon the driver, coupled with the other 5 labors incident to the management of the machine, a few hours work exhausts him. For this reason various efforts, attended with more or less success, have been made to operate the carrier by power furnished by the draft of the 0 machine.

My improvement, so far as it relates to this feature, consists in connecting the lever-arm by which the carrier is swung with arack-bar, which engages with a pinion on the harvester 5 to throw the carrier open, and by means of a treadle and friction-brake may be retained against the stress of the carrier after said pinion has ceased to actuate it until the load is entirely cleared.

In the drawings, Figure 1 is a top plan view (No model.)

of so much of a harvester (the binding attachment being omitted) embodying my invention as" is necessary to an understanding thereof. Fig. 2 is a rear elevation of the parts shown in the preceding figure; Fig. 3, a diagrammatic elevation from the stubble side of the machine; Figs. 4, 5, and 6, enlarged details of the rackbar and accessory mechanisms. Fig. 7 represents in rear elevation means whereby the special carrier invented by me may be operated by hand, and Figs. 8 and 9 are respectively a side elevation and a section of the preferred construction of the mechanism for operating the rackbar.

- A represents the elevatorframe, which does 6 5 not or need not differ from the usual shape.

Bis the rear sill, and B the front sill; C, the end sill on the stubble side; D and D, the lateral beams constituting the wheel-frame, and E the main wheel.

F is the bindingtable or decking, prolonged by a discharge-chute, F; but I have shown no binding mechanism, as my invention is irrespective of any particular type of automatic binder, and the parts already enumerated are to be taken only as exponents of a very general class.

Suitably secured adjacent to the front sill, and parallel therewith, is a bar, G, projecting out from the machine and having at its extreme end a low standard, 9, provided with a bearing near its top; but this standard may be omitted if it is seen fit to place the bar at a higher elevation. From the rearstruts of the elevator-frame, or from othersuitable support, projects another bar, G, in a plane parallel with the first, but so that its outer end is higher than the outen. end of that, and this Iastnamed bar has at said outer end a journal bearing, 9, still considerably higher than the journal-bearing in the standard 011 the other.

The carrier H may be constructed in any suitable manner and of anysuitable material.

It is shown for the purposes of this case as composed of parallel metal slats, h, pointing 5 in toward the harvester, riveted toacross-bar, h, and at the outer ends turned up and united by a strap, h, and this is perhaps the lightest and most durable form in which it can be embodied. At both front and rear it has verti- IOO cal arms if, both rigidly secured to the cross bar, and therefore directly opposite each other,

but the rear arm being somewhat longer than the other. These arms or bails carry pivot- 5 pins at such relative height on each that when set into the bearings at g and g, respectively, the carrier will be supported by them horizontally so long as it is in the receiving positio-n.

To the rear bail is secured a lever-arm, 2', with which is pivotally connected one end of an operating bar or rod, 1, extending to the elevator and there either provided witha handhold, as in Fig. 7, that the driver may open I5 the carrier by main strength, or else witha rack, 2", for engagement with a pinion, where by it may be operated bythe draft of the team. Other means may be adopted to open a carrier of this construction, it being understood, of course, that it is intended to gravitate back to receiving position. It is evident that with this construction, whenever the carrier is opened, its rear supporting-bar will make the longest sweep, taking that side of the carrier farther from the binder than the other and lifting it higherthat is, to a level with its rear pivot. A gap will thus be caused between the binder and carrier and between the ground and the ends of the carrier-slats that increases constantly in dimensions from front to rear, so that the onward movement of the machine will take the carrier from the pile of shfiaves as a housewife draws a mold from the 3e y.

In order to utilize the power of the team in operating the carrier,whether it swings on two axes or but one, a pinion on some constantlydriven shaft of the harvester, convenient for the purpose, is arranged to be engaged with 0 the rack-bar I, either intermittently or permanently. In the first case the pinion will be keyed to its shaft and run therewith; butin the second it will be loose on the shaft and clutched thereto only when the carrier is to 5 be opened. One arrangement is indicated in the first six figures of the drawings and the other in the eighth.

Proceeding to describe the first-indicated method: In harvesters and binders manufactured by the McCormick Harvesting Machine Company the reel is usually driven by a telescopic tumbling-shaft, K, extending from the rear, .where it receives motion through a sprocket-wheel, K,over the foot plank 7a, to its connection with the reel-supports, as shown,

for instance, in Letters Patent N 0. 270,910,

- granted January 23, 1888, to said company as assignee. Upon the rear member of this shaft, which is mounted in fixed bearings, I key a pinion, 7c, in such position that it will come immediately above the rack-bar, which is so confined in a guide loop or keeper, k", that it may be moved toward or from the pinion to bring it into or throw it out from engagement therewith. A strong plate-spring, l, with its effective face parallel with and pressing upon the teeth of the rack, serves not only to constantly urge it away from the pinion and to the bottom of the guide-loop, but also as a brake whereby the rack-bar may be temporarily held from retrogression after being disengaged from the pinion, to keep the carrier open until its load is entirely cleared. A treadle or footlever, L, is pivoted to one of the brackets Z, which carry the bearings for the tumbling-shaft, or to any other convenient support above the foot-blank, so that it may be operated by the driver in his seat. At the rear end this lever is-bent down and brought beneath the rack-bar opposite the pinion, or thereabout, and is provided with an anti-friction roll, Z", for contact with said bar. .By depressing the lever the bar will be raised against the force of the spring and brought into engagement with the pinion, which will instantly act to draw it in, thus swinging the carrier out and discharging the load. WVhen the carrier is fully opened, the driver will releasethe treadle sufficiently-to disengage it from the pinion, but will still hold it against the spring, now acting as a .brake, with sufficient force to prevent the carrier from closing until the load has fully escaped.

In the second method, as illustrated in Figs. 8 and 9, the spring is dispensed with, the rack-bar is confined closely in its loop and in constant engagement with its pinion, the pinion is mounted loosely upon its shaft, and has a friction-disk, m, on its rear face, while a countendisk, m, is keyed to the shaft, so that the pinion will be clutched to said shaft Whenever jammed against the connter-disk with sufficient force. On a bracket adjacent to the hub of the pinion is pivoted a short lever, N, having acollar, a, loosely embracing the shaft and arranged to be brought against the end of the pinion-hub to press it toward the disk. A bell-crank treadle, O, is pivoted to a low standard on the foot-board and connected with the power end of lever N by means of the link 0. To insure a steady frictional grip, a spring, 0, is interposed between the link and the treadle-arm, to which it is connected, and a not provided to adjust this spring.

As thus far described, these parts are sufficient to insure the action of the pinion upon the rack-bar and the retention of the latter while the load is being cleared, since according to the degrees ofpressure upon the frictionclutch the carrier will be opened or merely held open, or allowed to close, the clutch either driving the pinion or acting as a brake tohold it and the rack-bar stationary, or releasing it altogether; but as it sometimes happens that the bundle-carrier is accidentally tilted, I propose to lock it against movement until the pinion is clutched to its shaft. For

this purpose a fork is made in the link, one

arm, 0,of which is hooked and passes through an elongated slot in the end of the lever N, while the other, 0", is passed through a guide in the standard which supports said lever, and

its end brought immediately behind the end of the rackbar to prevent it from moving inward until the treadle is depressed, which action will first withdraw the locking-arm 0 without disturbing the lever N, owing to the play of the other arm in the recess, and then bringing said latter arm against the inner side of the recess will actuate the lever and cause the engagement of the friction clutch.

The forked link is constantly under stress to return to the locking position through the instrumentality of a spring, P,pressing on the end of the hooked arm, so that the inst-ant the treadle is released it will fly back to that po sition unless otherwise restrained. Such restraint is afforded, so long as the carrier is open, by the contact of the locking-arm with the side of the rack-bar, which bars its passage; butas soon as the end of this bar is reached, which will be at the moment the carrier is en tirely closed, the restraint ceases and the locking-arm shuts in past said end, as before.

Having thus described my invention, what I claim as new,and desire to secureby Letters Patent, is
